How to convert result created with dupliverts into editable meshes?
You can use the "Make Duplicates Real" function Ctrl+Shift+A. This will generate one object for each duplicate, but the generated objets will still share the same mesh. You can join them Ctrl+J to make a single mesh with all the cylinders. You can then separate each to an object with its own mesh by going to edit mode and P "By loose parts".
